ELECTRIC LAMP.

Specification of Letters Patent.

Patented Aug. 12,1913.

Application filed March 7, 1913. Serial No. 752,644.

To all whom it may concern Be it known that I, FRANKLIN H. HART, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Electric Lamps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a front view of an electric lamp constructed in accordance with my invention, shown in the closed position. Fig. 2 a perspective view showing the lamp in the open position. Fig. 3 a rear View. Fig. 4: a side view. Fig. 5 a top view. Fig. 6 a sectional view on the line a,b of Fig. 3. Fig. 7 a sectional view on the line cc5 of Fig. 3.

This invention relates to an improvement in electric lamps, and particularly lamps for limousines, sleeping car berths or any places where an electric lamp is desired, and where it is desirous to protect the lamp when not in use, the object being a simple construction in which the lamp is fully protected when not in use and which is readily brought into position for use, and which when brought into position for use makes proper connection with the lighting circuit, and the lamp so arranged that its rays will not be obstructed; and the invention consists in the construction as will be hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ a suitable frame 2 adapted to be secured in proper position, this frame being formed at the back with inwardly projecting centrally arranged lugs 3 and 4 for the purpose as will hereinafter appear. The frame is formed with a rectangular opening to receive a lamp casing 5 which is substantially triangular in cross-section, two of the sides 6 and 7 being of metal and supporting a reflector 26; while the other side is open, or it may be closed by a bowed glass 8 as indicated in Fig. 6 of the drawings. This casing includes a collar 27 at the top in which is mounted an incandescent electric light bulb 9 of usual construction, the upper end or socket 10 being seated in a circular recess 11 formed for it in the lug 3. This socket includes contact points 12 and 13 adapted to be engaged by contact-fingers 14: and 15 connected with the lighting circuit. At the bottom of the casing is a hub 16 carrying a pinion 17 in mesh with a gear or segmental rack 18 pivotally mounted at the inner end of the lug 4:. Connected with this segmental rack 18 are push buttons 19 and 20 which extend through the casing below the front opening therein. The hub 16 is formed with a transverse slot 21 within which is eccentrically pivoted an arm 22 projecting through a bearing finger23 extending rearward from the lower part of the case. This arm is formed with a shoulder 24 and upon the arm between the shoulder 24: and the finger 23 is a coiled pring 25 the tendency of which is to move the hub and hence turn the lamp casing.

In the closed position the side 7 of the lamp casing closes the opening in the frame, and at this time one of the push buttons is out and the other in. Preferably and as usual with lamps, one button will be white and the other black. If the black button is in and it is desired to expose the light the white button 19 will be pushed in, and this inward movement of the button turns the segmental rack 18 so as to turn the pinion 17 and rotate the lamp casing one third of a revolution so as to present the open or glazed front 8 thus exposing the lamp. This turning of the casing brings the contacts 12 and 13 beneath the contact-fingers 14 and 15 so as to close the circuit and light the lamp. The inward movement of the button 19 has projected the button 20, and the inward movement of the button 20 will reverse the position of the lamp casing and extinguish the lamp. The finger 22 being eccentrically connected with the hub assists in holding the lamp casing in one position or the other.

I claim 1. The combination with a frame having an opening and inwardly projecting, c-en t-rally arranged lugs, of a casing triangular in cross-section pivotally mounted between said lugs, two sides of the casing being closed, a lamp within said casing, and means for turning said casing whereby either the opening or one of the closed sides of the casing will be exposed through the opening in the frame, and means for opening or closing the lamp circuit.

2. The combination with a frame formed with an opening, and with inwardly prO- jecting centrally arranged lugs, of a lamp casing pivotally mounted between said lugs, an electric lamp in said casing, contactfingers supported by the frame and adapted to make and break connection with the electric lamp, and means including push buttons for turning the lamp casing.

3. The combination with a frame formed with a rectangular opening and with inwardly projecting lugs, a lamp casing pivotally mounted between said lugs, an electric lamp supported in said casing, contact fingers adapted to make and break electrical connection through said lamp, a pinion carried by said casing, a rack meshing with said pinion, and push buttons connected with said rack whereby the lamp casing may be turned.

4. The combination with a frame formed with a rectangular opening, a lamp casing pivotally connected with said frame, a lamp mounted in said casing, means for opening and closing an electric circuit through the lamp, a hub at the bottom of the casing, a pinion connected with said hub, a rack meshing with said pinion, push buttons connected with the rack and projecting through the front of the frame, and a spring-finger eccentrically connected with the hub.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
